I've researched this topic extensively, and the coincidences are undeniable.
Two types of elven castes once inhabited both Svargrond and Liberty Bay:
- Chelabdil in Svargrond
- Cenath in Liberty Bay.
-Ferumbras, in his quest for ancient artifacts, visits Svargrond. There, he imprisons Yakchal within a sarcophagus.
- Similarly, we know that Ferumbras has his own Citadel in the Shattered Isles, where an elven brooch is found, hinting at his elven bloodline.
- Both locations are occupied by Cults working for Ferumbras
- Both cults aro also involved in summoning the Triangle of Terror in those islands.
It's known that there are two type of elven Dreamborns:
- Summer and Winter courts. Intriguingly, these correspond to the elven castes of both cities.
Furthermore, both places harbor Bonelords' bases.
I believe these Bonelords are there to harness the souls of the fallen elves from these lands for their experiments. This involves fusing their souls with other corspes, as gleaned from some Bonelords' texts.
In summary, these two islands represent a duality tied fundamentally to the elven castes. In a distant past, they were inhabited by said castes who possessed artifacts and knowledge for Ferumbras Interest.
This is an image with those concepts summarized and some personal speculations regarding Zoralurk xD

NPC Malunga in Liberty Bay:
Player: civilisation
Malunga: The little we know about the extinct civilisation hints about a magically advanced race of humanoids, possibly of elven heritage, that once inhabited those isles until the disaster struck ...
Malunga: They were probably quite adept in manipulating the magical currents that are extremely strong on these isles.
